Insane flip
Set the realism to 100%. Select the Stanger as your car and start a single player race in Peakview. When the race starts, drive into the pits to the left where the cars and trailers are parked. Drive to the right end until you hit the wall, then turn around and look down the aisle of cars. You should see the front end of a blue Ford minivan with people on top of it. Drive toward it as fast as you can, turn slightly to the right, then hit on its side. If done correctly, you will flip through the air and land on your wheels.
